Bleh,
I forgot to mention, if you have to maintain controller action code
that is dependent on instance variables set elsewhere, here is a ruby
hack that will allow you to setup the context. (Please note, I
recommend refactoring the code under test but I understand sometimes
the preconditions of a test need to be a little....slimy. However,
both the code and the spec are smelly)
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
require File.expand_path(File.dirname(__FILE__) + '/../spec_helpers/
controller_behaviors')
describe SomeController do
stub_all_filters!
describe "#foo" do
def do_get
get :foo
end
it "should do something" do
controller.send(:instance_variable_set, "@bar", "here's bar")
do_get
end
end
end
class SomeController < ApplicationController
def foo
p "need to do something with #...@bar}"
end
end
Here's a gist in case the code formatting goes awry http://gist.github.com/142050

Hey Ignacy,
I think I'm in the minority on this one, but I tend to keep my
action logic independent of filters. Doing that, my typical
controller spec begins like this:
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
require File.expand_path(File.dirname(__FILE__) + '/../spec_helpers/
controller_behaviors')
describe SomeController do
stub_all_filters!
describe ...
...
end
The method "stub_all_filters!" is a custom rolled, per project
maintained, rspec hack that rips through Rails's internal methods to
find the filters on a controller and creates a "before do ... end"
that stubs each filter to "true" [1]
I still use before filters because it's a good fit for many plugins
such as ssl_requirement and authentication. However 1) I don't
explicitly split up controller action behavior into filters and 2)
the controller actions can depend on the filters indirectly by
consuming methods like "self.current_user"
I know you're maintaining prior-written code, but I thought this
would be relevant. I hope this helps more than it confuses.
